Question regarding dcache flushing for arm(specifically armv8, cortex A53)
|
varun sharma <nurav251@...>
Hi All,
I want to flush dcache in cortex a53 arm cpu, but it seems it is not implemented for arm in zephyr
I can't see any dcache_flush() implementation for arm..
I see it is only available for arc and x86, and not for arm...
pls share any reason it is not implemented for arm?
and if i want to add this, any pointers or pr/commit for that?
Thanks,
Nurav
